Application filed February 12, 1921. Serial No. 444,422;

To all 107mm it may concern:

Be it known that I, ROBERT SHIELDS, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Adj ustable Chute Spring for Typesetting Machines, of which the following is a full, clear, and exact description.

This invention relates to typesetting machines and has particular reference to a means for mounting the chute spring thereon.

Heretofore the chute spring has been stationarily mounted on a machine and has depended entirely upon its swinging movement to permit of the passage of matrices of various thicknesses, very often resulting in the clogging of the machine at this point and transpositions in the line.

This invention contemplates and seeks for its main object to provide means for mounting the chute spring on the assembler entrance plate to admit of vertical adjust ments of the same, whereby matrices of various sizes may be accommodated between the assembler bucklers and the chute spring to minimize clogging and transpositions in the line.

Another object in view is to rovide a means for mounting the chute spring which permits of the lifting or moving of the same to an out-of-the-way position in order to remove matrices which have become clogged at this point.

A further object in view resides in the provision of a simple and effective means for readily shifting the chute spring and retaining the same in its various shifted positions.

The invention further aims to provide a device of the character described which is comparatively simple in construction, inexpensive to manufacture and which may be quickly and easily associated with all standard forms of typesetting machines now in general use without materially altering the same.

Vith the above recited and other objects in view, the invention resides in a novel construction, combination and arrangement of parts set forth in the following specification, pointed out in the appended claims and illustrated in the accompanying drawings, in which Figure 1 is a fragmentary side elevation a way of a typesetting machine with the adjustable chute sprin mounting applied thereto.

Figure 2 is a vertical sectional view taken approximately on the line 22 of l iigure 1.

Figure 3 is a horizontal sectional view taken on the line 33 of Figure 1.

Figure 1 is asimilar view taken on the line '-.t of Figure 1.

Referring to the drawings bycharacters of reference, 10 desi nates the assembler entrance plate, 11 the assembler entrance plate stationary guide, 12 the spaceband chute, 13 the assembling elevator, 14: the.

matrix delivery belt which is trained over the assembler belt pulley 15, and 16 the as.

sembler buffers.

The chute spring 17 is pivotally mounted as at 18 on the lower extremity of an arm 19. In the usual construction, the arm 19 -is permanently secured to the assembler entrance plate 10 by means of srews or other fastening elements. In the present embodiment, the arm 19 is provided with longitudinally spaced and aligned lugs 20 projecting from the rear face thereof having conical heads 21 which are received by the longitudinal slots 22 formed in the base plate 23 which is secured by the fastening screws 24 to the assembler entrance plate 10. The major portion of the slot 22 is provided with oppositely inclined side walls 25 which are recessed as .at 26 adjacent the lower end to permit of the insertion and removal of the heads 21 for attaching'or detaching the arm to the plate 23. A shifting pin 27 projects from the front face of the arm 19 and coacts with the slotted extremity 28 of a manipulating lever 29 which is pivoted as at 30 to the assembler entrance plate '10, adjacent the base plate 23. 'The slotted extremity of the lever 29 is offset as at 31 and the opposite extremity frictionally engages and coacts with the assembler entrance plate to retain the lever and arm 19 in their shifted position against casual or accidental displacement. The extreme free outer end of the lever 29 is upturned as at 32 to provide a manipulating handle.

Tn use and operation of the device, by shifting the free end of the lever 29 downward, the pin and slot connection 27 and 28 between the lever and the arm 19 will effect the lifting of the chute spring 17 from the assembler buffers 16 to vary the space therebetween for the accommodation of matrices ofvarious thicknesses, the frictional engagement of the lever 29 with the asembler entrance plate servin to hold the same in its shifted position. l hikewise, the shifting of the outer extremity of the leverupward will lower the lower extremity of the chute spring for reducing the space.

between the same andthe buffers 16 to accommodate matrices of a narrower gauge, Should the matrices clog the machine at this point, the outer free extremity 32 of the lever may be shifted downward to the limit of its movement, thereby lifting the lower end of the chute spring and effecting a sufficient separation of the same from the huil'crs 16 to remedy the trouble. If desired, grzuluations 33 with suitable indicia may be inscribed on the arm and base plate for the purpose of visually indicating to the operator the adjustment of the chute spring for various thicknesses of matrices.

While there hasbeen illustrated and described a single and preferred embodiment of the invention, no limitation is necessarily made to the precise structural details, asit' is to be understood that variations and m0difications which pro erly fall within the scope of the appenced claims may be resorted to when found expedient.

I claim:

1. In a typesetting machine, means for mountingthe chute spring thereon for vertical adjustments whereby to permit of variation ofthe space between the free end of the chute spring and the assembler buffers and means coacting with the first means for efiecting vertical movements thereof whereby to ,obtain adjustments of the chute spring, means frictionally coacting with the assembler entrance plate to retain the chute spring in its adjusted positions.

2. In a typesetting machine, 'ertically slidable means to which a chute spring is connected whereby upon movement of said means the space between the free end of the chute springsand the assembler buffers may I be varied said means comprising an arm mounted for vertical sliding movements on the assembler entrance plate, and means pivoted on the assembler entrance plate coacting with said arm for shifting the same and frictionally coacting with the assembler entrance plate for retaining the arm in its shifted positions.

3. In a typesetting machine, adjustable with the base plate for vertical sliding-move ments, and means pivotedto the assembler entrancevplate adjacent the base plate hav ing operative connection with the arm. whereby upon swinging of said means the arm will be shifted vertically, said means frictionally engaging the assembler entrance plate whereby said arnris retained in its shifted positions.

4. In a typesetting machine, adjustable means for mounting the chute spring there- .on for vertical adjustments whereby to permit of variation of the space between the free end of the chute spring and the assembler buffers, said means comprising a vertically slotted base plate secured to the assembler plate between the assembler plate guide and the spaceband chute, said base plate having a vertical slot, an arm having the chute spring pivoted to its lower extremity provided with vertically-spaced lugs on the rear face thereof,said lugs a-dapted to coact with the slot for associating the arm with the base plate for vertical sliding movements, a pin projecting fromthe front face of the arm, and a lever pivoted adjacent said base platehaving a slotted end adapted to ROBERT SHIELDS.
